A silicone rubber extruder is a commonly used piece of equipment in the production of silicone rubber products. Whether it’s for pelletizing or for extrusion molding, extrusion machinery is indispensable. When purchasing an extruder, we typically focus on quality, output, price, and after-sales service. So, what factors influence the production capacity of a silicone rubber extruder?

The following explains… Silicone extruder Factors Affecting Production and Precautions for Prolonged Shutdowns

What factors affect the output of a silicone extruder?

Impact Silicone extruder The primary factor determining output is the extruder model. Silicone extruders are classified according to the diameter of their screw; the larger the equipment’s model number, the greater its capacity to process raw materials during production, and thus the higher the throughput.

So, what factors influence the output of silicone extruders of the same type?

The first point is feed capacity: if the equipment’s feeding system can’t supply material, the output will inevitably be poor.

Another factor is the screw design of the extruder; the thread depth and pitch must be properly engineered to influence production performance. Therefore, when selecting a silicone extruder, it’s advisable to choose a reputable manufacturer with strong technical expertise, as this can help minimize malfunctions and boost production efficiency.

Precautions for Silicone Extruders When Left Unattended for Prolonged Periods

Many silicone product manufacturers use silicone extrusion equipment in their production processes. For example, companies that produce silicone tubes, silicone sealing strips, LED strips, neon light tubes, medical urinary catheters, and other similar products all rely on silicone extruders. So, if… Silicone extruder Due to certain objective reasons, the equipment has remained idle for an extended period. What precautions should be taken before resuming operation? Below is a detailed overview of the key considerations when restarting a silicone extruder after prolonged inactivity, intended to assist you.

Precautions when the device remains powered off for an extended period:

1. Clean the material storage bin and hopper, and after confirming that there are no impurities or foreign objects, fill the storage bin with material. All metering and feeding devices shall be calibrated on-site in accordance with industrial requirements, and feeding curves for each device shall be provided; a commissioning plan shall also be agreed upon.

2. Verify that the thermocouples, melt sensors, and other sensing elements are installed correctly.

3. Verify that the electrical wiring is correct and secure, with no loose connections.

4. Use a megohmmeter to measure the heater; the heater’s insulation resistance shall not exceed 0.5 MΩ (for long-term failure).

5. Verify that all water pipes, oil lines, and vacuum pipelines are unobstructed and leak-free, and that all control valves operate smoothly and respond promptly to adjustments.

6. Verify that the host barrel assembly configuration is suitable for the material type to be processed; if it is clearly unsuitable, perform a new configuration adjustment.

7. Verify the rotation directions of the main motor and the feed motor: when facing the discharge head of the silicone extruder’s main unit, the main unit should rotate clockwise.

8. The extruder’s main unit is cooled with softened water.

9. Add lubricating oil to the housing until it reaches the midpoint indicated by the dipstick, then start the oil pump to circulate the lubricant, ensuring the oil level is at the dipstick’s midpoint.
